Librarians and pharmacists are driving hotel occupancy records in Seattle.

Tourism agency Visit Seattle says the 12 conventions between January and March this year will have generated 130,000 confirmed hotel rooms in the city, up from the previous record of 115,093 in 2007.

The American Library Association brought 9,000 library professionals to the city for five days in late January. The American Pharmacists Association will bring 6,000 visitors for four days later this month. And the annual Emerald City Comic Con, a meeting that generated 95,000 visitors during four days last year, also returns this month.

It’s all especially interesting, considering that nine of Seattle’s 10 coldest days have occurred in the months of January or February.

“It shows we’ve never been more popular,” says Visit Seattle President and CEO Tom Norwalk.
